NXP Semiconductors LPC2132FBD64,151

Overview

LPC2132FBD64,151 from NXP Semiconductors is a 16/32-bit ARM7TDMI-S microcontroller in LQFP64 package with 64 kB flash, 16 kB SRAM, one 8-channel 10-bit ADC, one 10-bit DAC (AOUT), and 47 GPIO pins - deployed in industrial control systems requiring analog sensing, PWM actuation, and real-time serial protocol bridging.

For engineers reviewing the LPC2132FBD64,151 datasheet, LPC2132FBD64,151 pinout, LPC2132FBD64,151 application, or LPC2132FBD64,151 equivalent, key selection criteria include its 60 MHz CPU clock, dual UARTs with hardware flow control, fast GPIO toggle capability (3.5× baseline), on-chip trace support, and 5 V tolerant I/O for mixed-voltage system interfacing.

Technical Context

The LPC2132FBD64,151 implements an ARM7TDMI-S core with Thumb instruction set support, enabling 32-bit performance at reduced code size (up to 30 % smaller vs. ARM mode). Its memory subsystem features a 128-bit wide interface and accelerator architecture for sustained 60 MHz operation from on-chip PLL.

Peripheral integration includes two 32-bit timers (four capture/compare channels each), six PWM outputs, embedded ICE RT and trace interfaces for real-time debugging, and dual Fast I²C-bus interfaces (400 kbit/s) with configurable pull-ups and glitch filtering on all 5 V tolerant I/O pins.

FAQ

What is the maximum operating frequency of the LPC2132FBD64,151?

The LPC2132FBD64,151 achieves a maximum CPU clock frequency of 60 MHz using its on-chip programmable PLL, which locks within 100 µs. This frequency is sustained via a 128-bit wide memory interface and accelerator architecture, enabling full 32-bit instruction execution without wait states under typical conditions. The LPC2132FBD64,151 maintains this performance across its specified −40 °C to +85 °C industrial temperature range.

Does the LPC2132FBD64,151 include a DAC, and how is it accessed?

Yes, the LPC2132FBD64,151 integrates a single 10-bit DAC accessible exclusively through the P0.25 pin, labeled AOUT in the datasheet. When enabled, the digital section of P0.25 is disabled to prevent noise coupling; the output voltage ranges from 0 V to VREF (typically 3.3 V). This DAC is absent in the LPC2131 variant but present in LPC2132FBD64,151 and higher members of the family.

How many analog inputs does the LPC2132FBD64,151 support, and what is their resolution?

The LPC2132FBD64,151 includes one 8-channel 10-bit successive approximation ADC (ADC0), supporting up to eight analog inputs (AD0.0–AD0.7) with guaranteed 2.44 µs conversion time per channel. All ADC inputs are mapped directly to physical pins (e.g., P0.27 = AD0.0) and are 5 V tolerant when configured as analog inputs. No second ADC bank is present - that feature is exclusive to LPC2134/36/38 variants.

What debug and trace capabilities does the LPC2132FBD64,151 provide?

The LPC2132FBD64,151 integrates EmbeddedICE RT for real-time JTAG debugging and an Embedded Trace Macrocell (ETM)-compatible interface with dedicated pins (P1.16–P1.19 for TRACEPKT[0:3], P1.20 for TRACESYNC, P1.24 for TRACECLK). This enables non-intrusive instruction trace capture at full CPU speed, supporting tools like Keil ULINKpro or Lauterbach TRACE32. The LPC2132FBD64,151 also supports on-chip RealMonitor software for semihosting and runtime analysis.

Is the LPC2132FBD64,151 pin-compatible with other devices in the LPC213x family?

Yes, the LPC2132FBD64,151 in LQFP64 package shares identical pinout and footprint with LPC2131FBD64/01, LPC2134FBD64/01, LPC2136FBD64/01, and LPC2138FBD64/01. All share the same SOT314-2 package outline and signal assignments. However, functional differences exist - e.g., DAC (P0.25) is active only on LPC2132FBD64,151 and above; ADC1 inputs are unavailable on LPC2132FBD64,151. PCB layout reuse is fully supported.
